T0 0J6 whom it may concern:

Be it known that I, J AMES BALL, a citizen of the United States,residing at Holyoke, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements inPaper-Cutting Machines,of which the following is a specification.

This invention relates to improvements in machines for cutting sheetswith oblique edges from webs of paper while the said webs are beingdelivered from the paper-making'machine, and is in the nature ofanimprovement on my patent of February 3, 1885, the object being toobviate the employment in such machines of a sheet-retarder, asdescribed in my said patent, and to, combine with a paper-making machinewhich delivers several webs of paper therefrom, or a web divided bycutting into several strips, a paper-cutting machine which receives saidseveral webs as they come in a continuous line from the paper-makingmachine, and cut sheets with oblique edges therefrom in such amannerthat the several cut sheets are caused to be dropped upon the ordinarylay-boy without the intervention of any devices for controlling theaction of the said sheets after they are cut off from the said webs.

In the drawing forming part of this specification, Figure 1 is aperspective view of a paper-cutting machine constructed according to myinvention, occupying an operative relation to the delivery end of apaper-making maadapted to operate with or without a size-tub,

B, whereby the paper is sized after, leaving the driers and before beingcut into sheets. A paper-cutting machine, D, is located at the end ofthe machine A, and is adapted to be run in connection with machineAby abelt from the latter over the pulley 2 on the cutting-machine, or byother suitable means, so thatthe latter will convey the paper webs c cat a speed corresponding to that of the machine A. Said Icutting-machine is provided with two rotating cutters,d d, each of whichoperates against the usual fixed cutter-bar. Said cutters are operatedby means of. gea'rconnections, as shown, with the drivingpulley 2 of themachine. Said cutters are hung in proper bearings in the frame of themachine D, and in lines oblique to theline of the movement of the paperwebs c,one above the other,as shown in Fig.1.

The cutters d d are adapted to act simultaneously upon the two webs c 0,so as to sever a sheet from each at the same time, forming sheets withoblique edges. Said sheets are both out and dropped at the same timeinconsequence of the peculiar arrangement of the said cutters, wherebyone sheet is not severed from the web before the other one, as is thecase where one diagonal cutter acts on two webs, as in my said patent,and hence the improved machine herein described and shown requires nosheet-retarder to hold back the first out sheet until the second one isout, and then releasing said'first cut sheet, so that both shall drop atthe same time onto the lay-boy; but by arranging in a paper-cuttingmachine two separate diagonal cutters, one above the other, and causingeach cutter to act at the same time upon the different webs, the severedsheets fall simultaneously upon the layboy, and they are thusmanipulated with as much ease and regularity as are several sheetshavingedges at right angles, and without any special devices whatever toguide the sheets, as aforesaid.

it is obvious that the wide web of a papermachine may be divided intomore than two strips,as shown,and that the number of knives on thecutting-machine may be made to correspond to the number ofseparate webson which they are to operate- It is obvious that paper from a machine,divided into two or more webs or that two or more separate webs may befed to the cuttingmachine from rolls of paper separate from thepapermachine, if desired, and be cut into sheets, as aforesaid; but themachine herein described and shown is especially useful forproducingsheets of paper with obliqueedges of the quality termed"loft-dried, since the webs c a, when treated with the sizing in tub B,are run off on the cutting-machine in a damp state, and the sheets arein that condition de IOO 2, Aplurality of cutters obliquely arranged andarranged in relation to each other and the webs, substantially as setforth,whereby rhomboidal sheets arecut by each from the Web on which itoperates, and the several sheets are delivered simultaneously to thelay-boy or carrier.

3. In combination with the frame and driv-' i ng mechanism of apaper-cutting machine, a plurality of cutting-rolls extending obliquelyacross said frame, the oblique-cutters on one roll being in a linetransversely of the machine with those of the next roll,substantially asshown.
